12. The city council is considering a law that would ban smoking in all public
facilities. A sample has been selected from the community and tested for support
of the ordinance. Is there a statistically significant relationship between age and
support for the anti-smoking law? Use the five step model as a guide and write a
sentence or two interpreting your results.

A. Use probabilities to determine if these two variable are independent or
dependent
P(Less than 40) =
P(Less than 40 |For) =
P (Less than 40 | Against) =
Are age and support for the anti-smoking law independent? (Yes = independent / No
= not independent)
B. Conduct a hypothesis test using an alpha of .05 that these variables are i
ndependent versus the alternative that they are related.

Total blood volume (in ml) per body weight (in kg) is important in medical research. For healthy adults, the red blood cell volume mean is about ? = 28 ml/kg.† Red blood cell volume that is too low or too high can indicate a medical problem. Suppose that Roger has had seven blood tests, and the red blood cell volumes were as follows. 34 23 40 37 28 38 29 The sample mean is x = 32.714 ml/kg. Let x be a random variable that represents Roger's red blood cell volume. Assume that x has a normal distribution and ? = 4.75. Do the data indicate that Roger's red blood cell volume is different from ? = 28 ml/kg? Use ? = 0.01.
